Ok. So we have that great mod for PC, and a whole bunch of nothing for consoles. That's why I'm here.
Idea
This involves at least alchemy and enchanting as supporting skills. Let's imagine:
You have an Blacksmith Parchment Template and Chisel. When approaching ore node, you can harvest it or mark it on a template. When you first mark node in some zone, this very parchment becomes "bound" to zone and becomes "Harvester map",
This activity can be introduced with new passive in each crafting skill line, with a few tiers:
1. Allows you to mark nodes with 50% chance to destroy node;
2. Allows you to mark nodes with 25% chance to destroy node;
3. Displays an amount of marked/total nodes for zone;
4. Allows you to make routes using map;
Using map grants you permanent buff which displays nodes of certain type on your in-game map and greatly increases visibility of source nodes with beams like skyshard ones.
Buff expires when you harvest x4 amount of map marked nodes.
Add your ideas and you are welcome to bully me for this.
